### 5/5 — The Cadillac of sudoku games.

*2025-04-08*

I have been playing this game for many years, and it is the most creative of all the sudoku apps I’ve tried. Besides the daily master puzzles, I love to enter challenging puzzles from other sources, and complete them without paper erasures. I love the variety of colors, typefaces and grid styles. I also love the “rewind” function that enable you to scroll back to a possible error.

### 3/5 — Missing landscape rotation

*2025-01-01*

Love this app, but I often use my ipad in landscape orientation so it sits on my lap and I don’t have to hold it. This app does not rotate which is a very basic UI requirement which means I can't use the app. Developers - please add app rotation!!!!!!!!

### 5/5 — I like it

*2024-11-06*

Perfect for relaxing
